Abstract

A data storing unit includes a plurality of areas divided in a predetermined range. A data writing unit writes, when reception data is received from outside, the reception data and a reception status indicating a status of the reception data in one area of the data writing unit collectively with a single writing operation, in such a manner that the reception status is located at an end of the one area.

1 . A storage control apparatus that stores reception data and a reception status indicating a status of the reception data, the storage control apparatus comprising: 
 a data storing unit that includes a plurality of areas divided in a predetermined range; and    a data writing unit that writes, when the reception data is received from outside, the reception data and the reception status in one area of the data writing unit collectively with a single writing operation, in such a manner that the reception status is located at an end of the one area.    
   
   
       2 . The storage control apparatus according to  claim 1 , wherein 
 the reception data is written right in front of the reception status in the one area.    
   
   
       3 . The storage control apparatus according to  claim 1 , wherein 
 the reception data includes first data and second data, and    the data writing unit writes the first data, the second data, and the reception status in the one area collectively with a single writing operation, in such a manner that the reception status is located at the end of the one area and the first data and the second data are located right in front of the reception status in order.    
   
   
       4 . The storage control apparatus according to  claim 2 , wherein 
 the reception data includes first data and second data, and    the data writing unit writes the first data, the second data, and the reception status in the one area collectively with a single writing operation, in such a manner that the reception status is located at the end of the one area and the first data and the second data are located right in front of the reception status in order.    
   
   
       5 . The storage control apparatus according to  claim 3 , wherein 
 the first data is embedded data indicating control information of a software, and    the second data is application data.    
   
   
       6 . The storage control apparatus according to  claim 4 , wherein 
 the first data is embedded data indicating control information of a software, and    the second data is application data.    
   
   
       7 . The storage control apparatus according to  claim 1 , wherein 
 when there is an error in the reception data, the data writing unit writes an error flag instead of the reception status.    
   
   
       8 . The storage control apparatus according to  claim 2 , wherein 
 when there is an error in the reception data, the data writing unit writes an error flag instead of the reception status.    
   
   
       9 . The storage control apparatus according to  claim 3 , wherein 
 when there is an error in the reception data, the data writing unit writes an error flag instead of the reception status.    
   
   
       10 . The storage control apparatus according to  claim 1 , further comprising: 
 a data updating unit that sets, when updating the reception data stored in the data storing unit, a writing start address of the reception data to integer multiple of a memory alignment determined in advance or a block size determined in advance.    
   
   
       11 . The storage control apparatus according to  claim 2 , further comprising: 
 a data updating unit that sets, when updating the reception data stored in the data storing unit, a writing start address of the reception data to integer multiple of a memory alignment determined in advance or a block size determined in advance.    
   
   
       12 . The storage control apparatus according to  claim 3 , further comprising: 
 a data updating unit that sets, when updating the reception data stored in the data storing unit, a writing start address of the reception data to integer multiple of a memory alignment determined in advance or a block size determined in advance.    
   
   
       13 . The storage control apparatus according to  claim 7 , further comprising: 
 a data updating unit that sets, when updating the reception data stored in the data storing unit, a writing start address of the reception data to integer multiple of a memory alignment determined in advance or a block size determined in advance.    
   
   
       14 . A storage control method of storing reception data and a reception status indicating a status of the reception data, the storage control method comprising: 
 writing, when the reception data is received from outside, the reception data and the reception status in one area of the data writing unit collectively with a single writing operation, in such a manner that the reception status is located at an end of the one area.    
   
   
       15 . A computer-readable recording medium that stores a computer program for storing reception data and a reception status indicating a status of the reception data, wherein 
 the computer program causes a computer to execute: 
 writing, when the reception data is received from outside, the reception data and the reception status in one area of the data writing unit collectively with a single writing operation, in such a manner that the reception status is located at an end of the one area.  
   
   
   
       16 . An information processing apparatus comprising: 
 a communicating unit that controls transmission and reception of information;    a storing unit that stores the information; and    a writing unit that writes, when the information is received via the communicating unit, the information in the storing unit by attaching reception status information indicating a reception status of the information to an end of the information.    
   
   
       17 . An information processing apparatus comprising: 
 a communicating unit that controls transmission and reception of information;    a storing unit that includes a plurality of areas for storing the information; and    a writing unit that writes, when the information is received via the communicating unit, the information in one area of the storing unit, and at the same time, writes reception status information indicating a reception state of the received information at an end of the one area.
